Nerf Gun
1. Load foam projectiles into magazine.
2. Insert said magazine into the magazine slot.
3. Pull back and push forward bolt to prime.
4. Pull trigger

[ Energy Conversion ]
When the bolt is pulled back and push forward, kinetic energy pushes a spring back within a compression chamber. When the trigger is pulled, the spring is released and will spring forward due to elastic potential energy stored in the spring. The kinetic energy in the spring then pushes air out of the compression chamber and said air will push out the foam projectile out of the gun.

STEPS
1) Push the hand of the MNM dispenser.
2) Wait for the MNM to fall on the cover where you can pick it up and eat !

THE SCIENCE BEHIND THE MNM DISPENSER & THE ENERGY CONVERSIONS
1) Chemical potential energy is obtained by a person.
2) The person pushes the MNM dispenser's hand so Chemical potential energy is converted to Kinetic energy.
3)Kinetic energy is then converted to Elastic potential energy which open  a little hole inside the dispenser to allow 1 MNM to pass through.
4) The MNM then reaches the end and out of the the dispenser.

( Sorry , I cannot send a picture because I cannot take picture from my computer and cannot copy paste from what I found on Google , which is what I have. )

This is another model of one of the many MNM dispensers !!!

AR - 001 (The first model of the Air Rifle rubber band gun)

Steps
1. Use a piece of rubber band and load it onto the gun.
2. Shoot. (Shown below)

How to make
-What to use
· 8 ice cream sticks
· 2 rubber bands - 1 for shooting
· UHU glue
-Making procedure
1. Arrange the sticks as shown below
2. Put UHU glue at all parts except the marked part as shown in the picture
3. Wrap a rubber band at the wrapped part
4. Load your rubber band gun and SHOOT CODE NAME ALPHA!!!

Explanation
When the rubber band is put onto the gun, the stretched rubber band possesses elastic potential energy. When the rubber band is released, the elastic potential energy is converted to kinetic energy, heat energy and potentially sound energy. The kinetic energy possessed by the  rubber band is then converted to the kinetic energy of CODE NAME ALPHA's face. LOL.

A music box

1.Wind up the music box by turning the key (wibd longer for a longer tune)
2.Let go
3.Enjoy the tune

Science behind the music box(I think):
Chemical potential energy from my finger is converted to kinetic energy as I turn the key. Kinetic energy of my fingers is converted to kinetic energy of the key. Then, Kinetic energy of the key is converted to the elastic potential energy of the spring, which is converted to kinetic energy of the gears. Finally, the kinetic energy of the gears is converted to sound energy.

a toy carolsel
STEPS:Hold the center tube and the carousel top. You should be able to hold both at the same time with one hand. With your other hand, wind up the toy by twisting the straw and rubber band.Let go of the carousel. It should spin quickly! Wind it up and spin again.

How to make:

1. print template on plain paper or cardstock. Color the carousel and top as desired.

2. Cut the paper template along the bold lines. Fold along dashed lines. Set aside.

3. Drill a ¼” diameter hole through the center of the plastic lid. (Adults only) If you don’t have a drill bit that large you can rotate the drill slowly as you make the hole to enlarge it.

4. Thread your straw through the rubber band and knot. Pull the loose end of the rubber band through the plastic tube. If you are using a narrow tube you can push the band through the tube using a toothpick.

5. Thread the rubber band though the hole in the bottom of the lid, thread a paper clip through the rubber band, and tape the clip to the inside of the lid.

6. Wrap the carousel template around the plastic lid. Tape the paper together to form a circle, then tape lower part of the template to the bottom of the lid. Add the paper top to the carousel and secure in place with glue.

THE ENERGY CONVERTION
The elastic poential energy from the stretched rubber band converts into kinectic energy to make the toy move.The toy will start out moving very fast and will eventually slow down and come to a halt.This is because the elastic potential energy had been fully converted into heat energy due to the frictional force,kinectic energy due to thee toy moving and sound energy.

A Toy Car

Steps:
~ Pull/move the toy car backwards
~ Let go of the toy car

Explain:
When the toy car is pulled backwards,the spring inside the car is compressed,so there will be elastic potential energy in the spring.When the toy car is released,the wheels will move the car forward,so there will also be kinetic energy when the car is released.When things move,there will be heat energy and there is also sound coming from the wheels when the car is moved,so there is sound energy in the wheels of the car.

The energy conversion:
The elastic potential energy of the spring when compressed will be converted into kinetic energy.Kinetic energy of the wheels when movedwill be converted into heat energy of the car and the heat energy of the car will be converted into the sound energy of the wheels.

Concept: Energy conversion.
Steps:
1.Push the toy downwards.
2.Place it on the floor.
3.Release it.
4.Enjoy!
Explain:
When I push the toy down, the chemical potential energy stored in my fingers is converted to kinetic energy.
It is then converted to elastic potential energy which is stored in the toy. When I released the toy, the elastic potential energy stored in the toy is released and is converted into kinetic energy . The kinetic energy pushed the toy up in the air, and some is converted to gravitational potential energy, and when the toy cannot go up any higher, the gravitational potential energy is converted back to kinetic energy. Hence landing on the ground.

How to make and use a handmade catapult steps:
1.Cut the bottom third off a cereal box.
2.Push a sharp pencil right through the box to make a pair of holes. Make another hole in the middle of the low side.
3. To make a catapult arm, make a cross out of two pencils and loop a rubber band around them to hold them in place.
4.Tape a shallow, plastic bottle lid to the bottom of the cross. Cut a rubber band and tie one end of it to the top of the cross
5.Fit the arms of the cross into the pair of holes you made.Push a sharp pencil right through the box above them and leave it there.
6.Push the end of the cut rubber band through the hole in the low side and pull it tight. Tie the end around a piece of drinking straw.
7.Make some balls of crumpled paper. Pull back the bottle lid, place a ball on top and let it go.
The Energy Conversion
When we pull back the catapult arm, the rubber band stores elastic potential energy. When we let go, the elastic potential energy stored in the rubber band will be converted to kinetic energy in the balls of crumpled paper.
P.S: The video will show you how to make catapults using ice cream sticks

(Don't know how to post pic)
There was elastic potential energy stored in the springs of the tire of the toy car. The elastic potential energy was then converted into kinetic energy when the toy car is pushed down. The elastic potential energy decreases and the kinetic energy increases. The more the toy car is pushed down, the more elastic potential energy is converted into kinetic energy.

Bouncing a ball
Concept:Energy Conversion
Steps:
1. Place the ball up high
2. Drop the ball and you are bouncing the ball !
Explain:When I place the ball up high,it has gravitational potential energy. When I drop the ball,gravitational potential energy is converted to kinetic energy so it moves. When it reach the ground,kinetic energy is converted to sound and heat energy due to friction,so the ball will eventually stop. The ball also bounces because it is made of rubber.

Concept: Energy Conversion
Steps:
1. Turn the knob of the toy a few times
2. Place the toy on the floor and watch it move around! Cute!
Explain:
When I turn the knob, the chemical potential energy stored in my fingers converts to kinetic energy of my fingers
It is converted to kinetic energy of the knob and is converted to elastic potential energy of the spring attached to the knob. When I released the toy on the floor, the potential energy stored in the wound-up spring is converted to kinetic energy and heat energy (due to frictional force) and sound energy of the moving toy. The toy eventually stops as all the kinetic energy has been converted to heat and sound energy.
